How do I check if a list is a subset of another list in Python using a conditional expression?

To check if a list is a subset of another list in Python using a conditional expression, you can utilize theall() function along with a list comprehension. Here's a detailed explanation of the process:
1. Using theall() function and a list comprehension: Theall() function returnsTrue if all elements of an iterable areTrue, andFalse otherwise. By combining it with a list comprehension, you can check if every element in one list is present in another list.

# Define the lists
list1 = [1, 2, 3, 4, 5]
list2 = [2, 4]
# Check if list2 is a subset of list1
is_subset = all(element in list1 for element in list2)
# Output the result
if is_subset:
print("list2 is a subset of list1.")
else:
print("list2 is not a subset of list1.")
In the example above,element in list1 for element in list2 is a list comprehension that checks if each element inlist2 is present inlist1. Theall() function is then used to evaluate if all elements in the list comprehension areTrue. If so, it means thatlist2 is a subset oflist1.
If all elements oflist2 are found inlist1, the output will be"list2 is a subset of list1.". Otherwise, if at least one element inlist2 is not present inlist1, the output will be"list2 is not a subset of list1.".
This method allows you to check if one list is a subset of another list using a concise conditional expression.
